x2+(y-43)2=782

Raise 78 to the power of 2.

x2+(y-43)2=6084

This is the form of a circle. Use this form to determine the center and radius of the circle.

(x-h)2+(y-k)2=r2

Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.

r=78

h=0

k=43

The center of the circle is found at (h,k).

Center: (0,43)

These values represent the important values for graphing and analyzing a circle.

Center: (0,43)

Radius: 78
